Abstract

The invention relates to sewage treatment filler which comprises resin, a dispersant, an antioxidant, a lubricant, a light stabilizer, a plasticizer, a flame retardant, a flexibilizer and a metal deactivator. The filler provided by the invention is of a honeycomb structure formed by a plurality of corrugated thin plates. The filler provided by the invention is free of problems of blockage and breakage and is long in service life. The filler as a macromolecular biological material is fast in biofilm culturing speed and high in adaptability to water quantity. The filler is a honeycomb living body. Beside biofilm culturing, the filler can be also used as a carrier for inclined plate settlement. An aeration tank and a settling pond are constructed in a combined manner, and a secondary sedimentation tank is reduced, so that the whole sewage treatment system is more compact, and the space and cost are lowered.

Description

technical field [0001] The invention relates to the technical field of sludge sewage treatment, in particular to fillers for sewage treatment. Background technique [0002] In the wastewater biofilm treatment process, the filled filler is the core part. Filler is the place where biofilm lives and the carrier of biofilm, which affects the growth, reproduction, shedding, shape and spatial structure of microorganisms, and also has the function of intercepting suspended matter. Thirdly, the filler plays the role of cutting and blocking the bubbles, which can increase the residence time of the bubbles in the water body and the contact surface area of ​​gas and liquid, and improve the mass transfer efficiency. It can be seen that the filler plays an extremely important role, and has a very important influence and significance on the operation effect and energy consumption of the biofilm process. At the same time, the cost of the carrier filler accounts for a large proportion of ...
